Claims.

The invention relates to window sashes, and has for its object a particularly simple double glass panel adapter frame for sashes originally intended to carry a single glass panel, which n adapter frame may be readily applied to the sash without modifying or materially modifying the sash. Many comparatively new railway cars,

buses, etc. are equipped with comparatively new The invention comprises, generally, a double glass panel adapted frame including a body for coacting with or resting on the inner edge of the sash on opposite sides of the channel provided in 'said sash for receiving the margin of the singleglass panel, the body bridging such channel and having a peripheral rib extending into or interlocking in the channel, and also having means for mounting spaced apart glass panels therein. Also, preferably the mounting means includes at least one removable glazing strip by which the glass panels may be easily removed and replaced without taking the sash frame apart or without removing one of the rails, usually the top rail of the sash.

The invention consists in the novel-features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like chard0 acters designate corresponding parts in all the views.

Figures 1, 2 and 3 are fragmentary isometric views of this double glass panel adapter'applied to a conventional form of sash.

I designates any one of the members of a sash, that is, the top or bottom rail or either one of the stiles, these being formed of metal to have a re-entrant channel 2 in which the margin of the single glass panel is located, together with a pack- 50 ing or lining 3 of rubber or other suitable material.

4 designates the adapter frame, this including a body mounted on the inner edge of the sash and coacting therewith at 5 on opposite sides of the Il channel and bridging the channel and having a (Cl, 18S-44) peripheral rib l extending into the channel 2, the

rib being located in the position usually occupied by the margin of the single glass panel. The body of the adapter frame is provided with means for mounting a pair of spaced apart glass panels with a sealed space between the glass panels,

this mounting includingat least one removable. glazing strip.

In Figure 1, the body is formed with a recess in the general form of an angular channel having a side wall or flange 1 and a bottom at 8, the f side of the adapter frame opposite to that on which the flange or side 'I is located, terminating near the level of the bottom 8. The mounting means is a strip Sof resilient compressible material, as rubber,'seated in the channel on the bot'- tom 0 vthrusting against a side wall 1, this strip being formed with a spacer I0 extending between glass panels II and I2. The strip is thus of such form as to provide a channel for receiving one glass panel l2 and a second channel open at one side for receiving the other glass panel II. The mounting means also includes a removable glazing strip I3 having a. base flange Il tting into a groove I5 formed in the body on the side thereof remote from the side wall 1 and a head portion I6 projecting above the bottom 8 of the channel and pressing against the outer face of themargin of the' glass panel II. The parts of this mounting thus form two channels for receiving the glass panels respectively and the side of one channel, being a removable glazing strip. The mounting, including the glazing strip, is of resilient compressible material, as rubber.`

The adapter frame is usually formed of metal. and that here shown, of extruded metal, and in order to lighten the same, the body is formed with recesses as I1.'

In the form shown in Figure 2, the mounting means includes two glazing strips I6", one for each glass panel II and I2, and the intermediate part Il of the mounting, including the spacer I0, is formed separate from the; glazing strips.

InFigure 3, an adapter yfor the same type of sash for a single glass panel is shown including 45 a body 40 having a pair of spaced apart peripheral ribs II which fit directly against the side walls of the re-entrant channel 2 of the sash instead of being seated inthe packing strip 3, as in Figure 1. In this form of the invention, the body is formed with a channel I9 located beyond the plane of the inner edge 5 of the sash and lapping onesideof the sash, this channel I9 receiving a glazing strip IBI. The side of the bodyA located opposite to that on which the channel U Il is located is provided with a side ilange 10 similar to the ilange 1. The mounting means l coacts with the body and the: flange 'I0 thereof in a manner similar to that shown in Figure 1, with the exception that the glazing strip is located in the outside channel i9.

Owing to the mounting means, as the strip i, or the mounting means shown in Figure 2, the margins of the glass panels are seated in a resilient compressible backing or mounting which is compressed transversely of the glass panels, so that the mounting has a give-and-take or a i'oilow-up action during variations in pressure of the air between the glass panels and the air on the outer sides thereof. Hence, the seals between the mounting and the glass panels are maintained indefinitely both between the spacer and the inner faces of the glass panels and between the outer glazing strip portions and the outer faces oi the glass panels, particularly at A, B, C and D.

By any one of the forms of this invention, a conventional sash intended to support but one glass panel may be easily and economically adapted to support double glass panels which are readily removable and which are practically sealed against exchange oLair in the space between the glass panels and the outer air. If desired, ventilation into the space between the glass panels may be provided in any well known manner or any well known dehydrating means may be employed.

What I claim is:

1. 'I'he combination with a window sash formed with a channel; oi a double glass panel adapter frame including a body for coacting with the sash on opposite sides of the channel and bridging the same and having a peripheral rib extending into the channel and also having means for mounting spaced apart glass panels therein.

2. The combination with a window sash formed with a channel; of a double glass panel adapter frame including a body for coacting with the sash on opposite sides of the channel and bridging the same and having a peripheral rib extending' into the channel and also having means for mounting spaced apart glass panels therein, said body and said mounting means forming a channel for receiving the margins of the glass panels and for providing a spacer between the margins of the arancia glass panels, the mounting means being of resilient compressible material.

3. The combination with a window sash formed with a channel; of a double glass panel adapter frame including a body for coacting with the sash on opposite sides of the channel and bridging the same and having a peripheral rib ex-v tending into` the channel and also having means for mounting spaced apart glass panels therein, said body and said mounting means forming a channel for receiving the margins of the glass panels and for providing a spacer between the margins of the glass panels, at least one side portion of the mounting constituting a removable glazing strip, the mounting means being of compressible resilient material.

4. The combination with a window sash formed with a channel; .of a double glass panel adapter frame including a body for coacting with the sash on opposite sides of the channel and bridging the channel and having a peripheral rib for interlocking in the channel, the body being formed with an angular channel having one side wall and being open at its other side, mounting means for double glass panels mounted in the angular channel, the mounting means being of resilient compressible material and including a spacer extending between the glass panels, and a removable glazing strip, the body being also formed with a lengthwise groove extending below the bottomof the channel, said glazing strip having va base flange located in said groove, and a head portion pressing against the outer face o! the adjacent glass panel.

5. The combination with a window sash formed with a channel; oi a double glass panel adapter frame including a body for coacting with the sash on opposite sides of the channel and bridging the same and having a peripheral rib extending into the channel and alsohaving means of resilient compressible material for mounting spaced apart glass panels therein including a removable glazing strip, the body being formed along one side thereoil with a channel located along the side of the sash beyond the edge of the glass panel and the glazing strip having a base ilange extending into the last-mentioned channel, and a head` portion pressing against the outer margin of the adjacent glass panel.
